The theory of reciprocal derivative chronopotentiometric analysis (RD-CPA) with a thick planar mercury electrode (TPME) is presented in this paper. The results, which show that the sensitivity of chronopotnetiometric analysis (CPA) is increased by about ten times, are in agreement with the theoretical analysis.
